Seaside Pleasures was originally published by the Society for Promoting Christian Knowledge as a series of topographical essays under that name in the 1852 series of Home Friend, and then re-published anonymously as a small book in the summer of 1853, with the addition of two other essays entitled "Valley of the Rocks".
    The Home Friend, initially published as a “penny weekly” and released every Wednesday as a numbered journal was also compiled into progressive volumes every 26 weeks; printed by W. Clowes & Son, Stamford Street and Charing Cross. The first journal, No. 1, was released on Wednesday, June 2^nd, 1852, and the first Volume contained No’s 1-26. The only other volumes I have viewed are Volume 2, No’s 27-52; Volume 3, No’s 53-78. These volumes cover the vast majority of Gosse's work including "Seaside Pleasures" and another short series about his visit 1853 visit to Lundy Island, later published as the opening chapters of "Sea & Land" in 1865.
    Seaside Pleasures is centred around the time Gosse spent in Ilfracombe during the summer and autumn of 1852, whilst experimenting and gathering specimens for Warington and London Zoo. The last essays, The valley of the Rocks, are attributed to Gosse's wife Emily by E. Gosse in "The Life of P. H. Gosse, FRS," London, 1890, pp242.
    The book, being anonymous, is very rare; the only copy I have viewed is held at the Natural History Museum, London. This being the case, I have identified each article in the weekly journal for those who wish to assemble their own book. The volumes of Home Friend are available at the British Library, London, with volumes 2 & 3 also held the University Library, Bristol.
